BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     A reading stand or like copy holder and light assembly for use therewith wherein both the reading stand and light assembly are selectively adjustable and removably attached to one another to facilitate placement of the light in a more efficient location relative to a copy or book retained on an exposed surface of the copy holder portion of the reading stand. 
     Description of the Prior Art 
     Reading stands and like devices more generically referred to as copy holders are used for a variety of purposes, generally associated with the support and position of various types of copy in a more efficient and exposed position relative to the user of such a stand. The prior art is replete with structures of the type set forth above, some of which include a lighting structure associated therewith and positioned to direct light directly on the surface or face of the copy or book being observed. Typically, stands of the type referred to herein include some type of longitudinally adjustable support arm holding a normally planar copy holder plate or the like at an angled position relative to an observer. The copy, which may include a variety of different objects, including books or magazines, is normally retained on an exposed surface of the copy holder in a preferred orientation for viewing. Other features also exist in the prior art relating to the retaining of the various pages in a preferred position and the support of the copy on the exposed face in such a manner that it can be removed and/or manipulated as by turning individual pages. 
     U.S. Pat. No(s). showing structures which are representative of prior art devices include 4,819,902; 4,014,508; 3,350,150; 3,200,791; and 2,732,481. 
     In light of the above structure, there is still a need and demand in this industry for a more efficient supporting reading stand and copy holder structure for the efficient presentation of various objects to be read or observed, while sitting in a comfortable, upright position, wherein a stand may be used in direct combination with a lighting assembly and/or wherein the lighting assembly may have a versatile structure applied thereto so as to allow it to be used independently of the reading stand for the efficient illumination of other areas. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a reading stand and also to a lighting assembly which can be used in combination therewith. Alternately, the lighting assembly is capable for independent use with a cooperative light supporting base unassociated with the reading stand per se. 
     The reading stand of the present invention includes a support assembly including a base having a supporting arm mounted thereon and extending upwardly therefrom. The support is telescopically structured so that its length may be adjusted. An opposite or upper end of the support arm has a copy holder having a substantially planar configuration adjustably mounted thereto and connected so as to be oriented relative to the upper end of the support arm at a variety of angles to accomplish sufficient positioning of books and like copy objects on an outer exposed surface thereof. A support plate is secured to a lower end of the copy holder and extends angularly outward from the exposed surface thereof. A stop plate is also provided adjacent to the support plate. The stop plate is angularly adjustable so as to engage the lower end of books or like objects, thereby ensuring that the pages do not inadvertently turn. A gripping pad or like member made of a somewhat flexible material and including a plurality of protrusions extending outwardly therefrom. The gripping pad is preferably secured to an outer exposed surface of the stop plate. The support plate and stop plate, therefore, serve the purpose of supporting the lower end of a book on the exposed surface of the copy holder while also serving to properly maintain the pages of the book in the intended, opened position. In addition, retaining means in the form of two retaining arms are secured to a general upper end of the copy holder and are exposed in depending, substantially overlapping relation to spaced apart portions of the cover of the book or like object maintained thereon. Such retaining arms are spring biased so as to be movable outwardly from the copy holder to allow positioning or removal of the book or other copy relative to the exposed surface of the copy holder. 
     The light assembly of the present invention includes a base having a somewhat hollow interior in which is mounted the electrical control and substantially conventional component which serves to power and activate a light source in the form of a light bulb secured within a light housing. A support member having a plurality of innerconnected and adjustably attached segments serve to innerconnect the light housing to the base. The adjustable innerconnection of each of the plurality of segments is such as to allow adjustable selective positioning of the housing relative to the exposed surface of the copy holder and any copy maintained thereon. The base is removably attached to the under surface of the copy holder through the provision of mounting means formed both on the under surface and on the base itself. 
     An electrical conductor means is removably attached to the base and serves to innerconnect the interior activating electronic control and components to a conventional power source for energizing the light source within the light housing. This same conductor means is usable with a second preferred embodiment of the present invention when the light assembly is used other than in direct combination with the reading stand. 
     In the second preferred embodiment, a light support includes an exterior housing having a hollow interior which is filled with a weighted material of sufficient density to adequately anchor the light assembly. Supporting innerconnection between the remainder of the light assembly and the light support occurs by the aforementioned base being disposed within an integrally formed socket. This socket extends substantially into the interior of the light support, but in segregated relation to the weighted material on the interior of the housing. The pocket has an opened upper end formed on an uppermost face of the housing and being dimensioned to allow a sliding, removable fit of the base portion of the lighting assembly therein. The aforementioned electrical conductor means, in addition to an elongated external conductor, further includes a male plug integrally or fixedly attached to the base. This male plug is disposed to fit within a female receptacle formed at the bottom, or other applicable location, within the pocket. An electrical conductor segment innerconnects the internal female socket to a male plug formed in the housing so as to communicate with the exterior thereof. The aforementioned external conductor, therefore, is attachable to the exteriorally accessible plug and is further structured to have its opposite end connected to a conventional electrical wall-type socket for powering of the light assembly. 
     Other features of the subject invention include the light housing in which the light source, in the form of a light bulb, is removably attached therein. A handle means, structured from a non-heat conducive material, is mounted on the exterior of the housing so as to accomplish its manual positioning and arrangement into a desired light illuminating position relative to the material being viewed or read. 
     Yet another feature associated with the housing is the provision of one of a plurality of plates removably disposed in covering relation to the light source and being formed from a transparent material so as to allow the illumination to pass therethrough. This cover plate is slidingly mounted and supported on a carrier structure mounted immediately adjacent to an open face of the housing over which the cover plate is positioned. The carrier is structured to include a receiving track-like structure in which the transparent material cover plate is slidably positioned. As set forth above, a plurality of such cover plates may be provided wherein one of the cover plates may be formed, at least in part, from a clear transparent material and the remaining cover plates may be formed from transparent material each having a different color. The light eminating onto the copy to be viewed or read will, therefore, be illuminated into different hues or color preferred by the reader or observer.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in FIGS. 1-4 one preferred embodiment of the present invention comprises a reading stand generally indicated as 10 having a light assembly generally indicated as 12 removably attached thereto. More specifically, the reading stand includes a support platform 14 dimensioned and configured to be positioned on any type of supporting surface such as a desk, table, etc. The stand 14 includes a support arm 16 having telescopically innerconnected segments 18 and 20 which enables the length of the support arm 16 to be varied thereby regulating the height of a copy holder generally indicated as 22. The copy holder 22 is connected at the upper end of the support arm 16 as at 24 in a manner which allows its angular adjustment relative thereto. The copy holder 22 includes an outer exposed surface 26 on which a copy or book 27 may be mounted in a manner shown in FIG. 1. The copy holder further includes a support plate 30 fixedly mounted to the lower end of the copy holder 22 so as to extend angularly outward from the exposed surface 26. As best shown in FIGS. 2 and 5, a stop plate 31 is mounted in an angularly adjustable position between the exposed surface 26 and the support plate 30. Such angular adjustment occurs through the provision of a hinge structure 32 interconnecting the stop plate 31 to the bottom of the copy holder 22. A knob 34 serves to angularly orient and position the support plate 31 so that it may be positioned to engage the lower end of the various pages 29 of the book 27, thereby preventing the pages 29 from inadvertently turning. To facilitate this, a gripping pad or like structure as at 33 is mounted on the stop plate 31. The gripping pad 33 is formed preferably from a flexible material such as rubber or the like and includes a plurality of depending fingers having an enlarged head as at 35 disposed to pass through apertures 37 formed in the stop plate 31. The outer surface of the gripping pad 33 has a plurality of protrusions as at 39 integrally formed therein and positioned to help grip the lower ends of pages 29 of the copy material or book 27 supported on the exposed surface 26 of the copy holder 22. The hinge 32 and manipulating knob 34 may include some type of locking structure to maintain the stop plate 31 in its preferred angular orientation as basically shown in FIG. 2. 
     Further, retaining means in the form of two retaining arms 38 are connected generally at the upper end 22&#39; of a copy holder 22 and depend downwardly therefrom in overlying, substantially covering relation to spaced apart portions of the exposed surface 26 and against the inside cover of a book or a copy 27 placed thereon. Each of the retaining arms 38 are connected as at 40 by spring biased connectors serving to normally bias the arms 38 into the aforementioned covering relation to the exposed surface 26 and in overlapping covering relation to the inner surfaces of the cover portions or other parts of the book 27. Due to the spring bias connectors 40, each of the arms 38 may be independently moved outwardly from the surface 26 and the copy so as to position or remove the copy as desired. 
     As shown in FIGS. 2, 4, and 7, the light assembly includes a base 44 which is removably attached to the under surface 29 of the copy holder 22 through the provision of mounting means generally indicated as 45 (See FIG. 2). As best shown in FIG. 7, the mounting means comprises two mounting fingers 46 extending outwardly from the under surface 29 and structured to be received within mounting apertures 48 integrally formed in the base 44 and passing at least partially into the interior thereof. The cooperative disposition and configuration of the mounting fingers 46 and the apertures 48 are such as to allow removable insertion of the fingers 46 into the interior base 44 through the apertures 48 as best shown in FIG. 7. 
     Other features of the light assembly 12 are shown in detail in FIGS. 8, 9, and 10. The base 44 has a hollow interior portion in which the electronic controls and components 47 are housed which serve to power and otherwise activate the light source in the form of a light bulb 49. The light bulb 49 is, of course, mounted within a light housing generally indicated as 50. A conventional electrical conductor as at 52 passes through a support structure or member comprising a plurality of support segments 54 innerconnecting the base to the light housing 50. Each of the support segments 54 are innerconnected in an articulated manner to one another by a plurality of adjustable attachments generally indicated as 58. 
     Other features of the light assembly are best shown in FIGS. 8, 9, and 10. As shown therein, the light housing 50 has a hollow interior terminating in an open face as at 70 through which light eminates from a light source in the form of a light bulb 49. A cover assembly including at least one of a plurality of cover plates 72 are each, individually, disposed to be removably supported in such covering position relative to the light bulb 49 by a carrier assembly 73. The carrier assembly comprises a mounting or carrier track along which a cover plate 72 slides into and out of covering position relative to the light bulb 49. Each of a plurality of cover plates 72 are formed in large part from a transparent material such as glass, clear plastic, etc. as at 74. Depending upon the cover plate used, the transparent material 74 may be clear or may be comprised of any one of a plurality of numerous colors. When a colored cover plate is disposed in overlying or covering relation to the light source 49, obviously, the copy or copy holder will force light to be eminated from the housing 50 in that same color or hue. A handle 75 is provided to freely manipulate the cover plate 72 into and out of its covering position. Also, a lock member 77 may be provided to engage the handle and maintain the cover plate 72 in a closed position. 
     The housing further comprises an adjustable or manipulating handle as at 76 disposed in continuous surrounding relation to the housing 50 and mounted on the exterior part thereof. This handle 76 is formed, at least in part, of non-heat conductive material so as to prevent heat from the light source 49 and housing 50 to be transmitted to the handle 76, thereby protecting the user. 
     Another embodiment of the present invention is shown in FIGS. 11 and 12. This embodiment comprises a light support generally indicated as 80 including a housing 82 having a somewhat hollow interior 84 which may be filled with a weighted material 86 of sufficient density to provide stability when the remainder of the light assembly 12 is attached thereto and extends outwardly therefrom. The housing 82 includes an integrally formed pocket 88 having an open end as at 90 formed in an uppermost face or surface 92 of the housing. The open end 90 is specifically configured and dimensioned to receive the base 44 of the light assembly 12 therein. As shown in FIG. 6, the base 44 includes a male type connecting plug 94 protruding from a lower most end thereof as at 44&#39;. This male plug 94 is designed to connect with a female plug or like receptacle 98 formed on the interior of the pocket 88. An internal electrical conductor as at 100 serves to innerconnect the interior female socket 98 with an external male plug type connector 101. An external conductor 102 is appropriately structured at one end to fit the male type plug 101 and has its opposite end substantially conventionally structured to fit within a wall socket (not shown). The embodiment of FIG. 11 and 12 may be used independently of the copy holder 22 when it is desired to efficiently position an illuminating source on any other surface for reading copy or the like. Naturally, the embodiment of FIGS. 11 and 12 could also be used with the reading stand as shown in FIGS. 1-4. 
     Now that the invention has been described,
